    This book describes IRF concepts and guides you through the IRF setup procedure. Hardware compatibility An HP 5130 EI switch can form an IRF fabric only with devices in the same series. IRF benefits IRF provides the following benefits: •...

  • Page 6: Basic Concepts

    Figure 1 IRF application scenario Basic concepts This section describes the basic concepts you might encounter when you work with IRF. IRF member roles IRF uses two member roles: master and standby (called subordinate throughout the documentation). When devices form an IRF fabric, they elect a master to manage and control the IRF fabric, and all the other devices back up the master.

  • Page 7: Irf Physical Interface

    To use an IRF port, you must bind a minimum of one physical interface to it. The physical interfaces assigned to an IRF port form an aggregate IRF link automatically. An IRF port goes down only if all its IRF physical interfaces are down.

  • Page 8: Irf Split

    IRF split IRF split occurs when an IRF fabric breaks up into two or more IRF fabrics because of IRF link failures, as shown in Figure 3. The split IRF fabrics operate with the same IP address and cause routing and forwarding problems on the network.

  • Page 9: File System Naming Conventions

    On the standalone switch Sysname, GigabitEthernet 1/0/1 represents the first port on the device. • Set its link type to trunk, as follows: <Sysname> system-view [Sysname] interface gigabitethernet 1/0/1 [Sysname-GigabitEthernet1/0/1] port link-type trunk On the IRF fabric Master, GigabitEthernet 3/0/1 represents the first fixed port on member device •...

In this example, the current working path is the root directory of the flash on member device 3.

  • Page 11: Irf Multi-active Detection

    Two members are considered to start up at the same time if the difference between their startup times is equal to or less than 10 minutes. For these members, the next tiebreaker applies. Member with the lowest CPU MAC address. For the setup of a new IRF fabric, the subordinate devices must reboot to complete the setup after the master election.

  • Page 12: Lacp Mad

    In contrast, BFD MAD, ARP MAD, and ND MAD do not compare the number of members in fabrics. These MAD mechanisms use the following process to hand a multi-active collision: Compare the member IDs of the masters in the IRF fabrics. Set all fabrics to the Recovery state except the one that has the lowest numbered master.

    Assigning a member ID to each IRF member device CAUTION: In an IRF fabric, changing IRF member IDs might cause undesirable configuration changes and even data loss. Before you do that, back up the configuration and make sure you fully understand the impact on your network.

  • Page 23: Connecting Irf Physical Interfaces

    Connecting IRF physical interfaces When you connect two neighboring IRF members, connect the physical interfaces of IRF-port 1 on one member to the physical interfaces of IRF-port 2 on the other (see Figure 10). For example, you have four chassis: A, B, C, and D. IRF-port 1 and IRF-port 2 are represented by A1 and A2 on chassis A, represented by B1 and B2 on chassis B, and so on.

    Follow the restrictions in "IRF physical interface requirements." • You must always shut down a physical interface before binding it to an IRF port or removing the • binding. Start the shutdown operation on the master, and then the member device that has the fewest number of hops from the master.

    Configuration prerequisites Make sure the device you are adding to the IRF fabric has sufficient storage space for the new software images. If sufficient storage space is not available, the device deletes the current software images automatically. If the reclaimed space is still insufficient, the device cannot complete the auto-update. You must reboot the device and access the Boot menu to delete files.
